For the sake of full disclosure, this is the most beautiful news I've seen all day today. I've been a committed fan to both Fire Emblem and XCOM since I was a lil rugrat catching that impressively long, epic Sacred Stones epilogue while the rest of the fam was doing things like eating dinner together.
I only ever dreamt we'd wake up in a world one day where a game might merge favorable elements from each differing game. This game is it, man, and all thanks to mods. The description reads:
“This mod puts a dash of Fire Emblem into your XCOM, leveraging a ‘squadmate score’ system to give small buffs for squads that trust in each other.”
